Few factors contribute so much to successful aging as healthy eating and regular physical activity, and it's never too late to start. Poor diet and lack of physical activity are the most important factors contributing to the increase in overweight and obesity in the United States, which in turn are major risk factors for many chronic diseases, such as heart disease and diabetes.

A team of researchers at the Pennington Biomedical Research Center in Baton Rouge, led by Dr. Eric Ravussin, is conducting research on calorie restriction and aging as part of the multi-center Comprehensive Assessment of Long-term Effects of Restricting Intake of Energy (CALERIE) trial, funded by the National Institute on Aging,

The study investigators recently made headlines by announcing results that indicate if you severely cut the calories you eat – by up to 25 percent for six months – while maintaining a nutritious diet, you are likely to be healthier and live longer. The researchers have planned a second calorie restriction study (CALERIE 2) that will examine certain biomarkers of aging and health indicators to try to determine if the study participants' improvement in health and aging slowdown was due to the calorie restriction or to their weight loss during the study.

I was reading the local paper the other day and ran across an article about weight loss and diabetics. The article reported on a study completed in Portland where researchers tracked weight gain and loss patterns of more than 2,500 people who were recently diagnosed with type 2 diabetes. Many of the subjects didn’t lose any weight, but a group of about 300 shed 20 pounds in the months after diagnosis. Four years later the group that shed some weight had better control of their blood sugar and blood pressure even if their weight loss was short-lived. Immediately losing weight after diagnosis seems to help with the long-term effects of type 2 diabetes. And, the author of the research study indicates, there is never a bad time to lose weight.

We have discussed in past months the impact of obesity and type 2 diabetes. Our state faces an epidemic unless we do something to get our young citizens to deal with weight-related health issues. We have to find ways to help young people maintain a healthy weight and make smart choices about diet and exercise. Each of us adults needs to be a role model. We need to practice what we preach.

Let's don’t let our children down. But, first, look in the mirror as I have done and, as they say on the airplane in case of an emergency, put your oxygen mask on first and then help others. Be selfish! Take care of yourself. Then reach out to others. Together we can!

Many people do not know the difference between type 1 and type 2 diabetes. Here is a brief explanation:

Type 1 diabetes is a disease that occurs because the body can’t make insulin, and sugar levels in blood get too high. Insulin is a hormone produced in the pancreas that the body needs to move glucose (sugar) from the blood into body cells to be used for energy. Type 1 diabetes used to be called juvenile diabetes and insulin-dependent diabetes. Most cases of type 1 diabetes develop in youth, but it can develop at any age. Five percent to 10 percent of all diabetes cases are type 1.

Type 2 diabetes is a disease that occurs because the body either can’t make enough insulin or can’t use insulin properly, causing sugar to build up in the blood. Type 2 diabetes was previously known as adult onset and noninsulin-dependent diabetes. From 90 percent to 95 percent of diabetes cases are type 2. Most cases of type 2 begin after age 30 or 40, but the number of children and teens with type 2 is increasing.
